8088 instruction set of Intel.
In the x86 assembly language, the TEST instruction performs a bitwise AND on two operands. The flags SF , ZF , PF are modified while the result of the AND is discarded. The OF and CF flags are set to 0 , while AF flag is undefined. There are 9 different opcodes for the TEST instruction depending on the type and size of the
There were two stages in history for the microprocessor. The first was the CISC (Complex Instruction Set Computer), which had many different instructions. In the 1970s, however, places like IBM did research and found that many instructions in the set could be eliminated. The result was the RISC (Reduced Instruction Set
Intel 8086. From Wikipedia, the free encyclopedia. The 8086[1] (also called iAPX86) is a 16-bit microprocessor chip designed by Intel between early 1976 and [3] It implemented an instruction set designed by Datapoint corporation with programmable CRT terminals in mind, that also proved to be fairly general purpose.

x86 is a family of backward-compatible instruction set architectures based on the Intel 8086 CPU and its Intel 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit-based 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a
The modern x86 instruction set is a superset of 8086 instructions and a series of extensions to this instruction set that began with the Intel 8008 microprocessor. Nearly full binary backward compatibility exists between the Intel 8086 chip through to the current generation of x86 processors, although certain exceptions do
This chip could also arguably lay claim to be one of the first microprocessors or microcontrollers having ROM, RAM and a RISC instruction set on-chip. The layout for the four layers of the PMOS process was hand drawn at x500 scale on mylar film, a significant task at the time given the complexity of the chip. Pico was a
